Suppose that a mutation resulted in a tapeworm that did not have hooks. Assuming this tapeworm was a human parasite, what is the most likely explanation of the effect might this have? The tapeworm would spread throughout the human body.   The tapeworm would complete its entire life cycle inside the human host.   The tapeworm would not remain in the digestive tract very long.   The tapeworm would not be able to enter the human body.   The tapeworm would reproduce more to compensate for a lack of hooks.

Parasitic infections

A parasite is an organism that lives in the body of another organism and obtains food at the expense of the host. There are two kinds of parasites they are internal and external. An internal parasite lives inside another organism and is known as endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite.
